Introduction
Th e information contained in this manual provides general guidelines for the implementation of ModBus and BACnet
communication with the Lochinvar Armor.
All ModBus networks are implemented utilizing a master-slave arrangement where all Armors are slaves and the master is a
building automation system capable of communicating over a RS-485 serial connection. BACnet networks are implemented
using a token passing protocol (MS/TP) where multiple masters and slaves share a common RS-485 bus. Th
e Lochinvar BACnet
interface is a master only.
